Answer (this one's written in slope-intercept form):


y= (3)/(5)x -3

Explanation:

1) Lines that are parallel to each other have the same slope. The line
y=(3)/(5) x-8 is in slope intercept form, or
y = mx + b form, and the number in place of
m represents the slope. Knowing this, it looks like
(3)/(5) is in the place of the
m in that equation, so
(3)/(5) is the slope - and the slope we need to use for the answer, too.

2) Once you know a point that the line must pass through and a slope, you can write an equation with point-slope form, or
y-y_1 = m (x - x_1).
m is the slope and
x_1 and
y_1 are the x and y values of the point it must pass through. So, substitute
(3)/(5) for
m, 0 for
x_1, and -3 for
y_1. Simplify and isolate y to put it in slope-intercept form:


y-(-3) = (3)/(5) (x - 0) \\y + 3 = (3)/(5) x - 0 \\y = (3)/(5) x - 3

3) Thus,
y = (3)/(5) x - 3\\ is the answer. It's written in slope-intercept form.
